Housing affordability: the use and misuse of reverse mortgages by older households. Many retirees are without compulsory superannuation although daily living costs have risen substantially. As additional workers in the 'baby boom' generation retire and less tax will be paid to the government, it appears there will be increasing pressure placed on the pension system. A large proportion of the population may struggle to enjoy a fulfilling retirement and be drawn towards a reverse mortgage, which ....Housing affordability: the use and misuse of reverse mortgages by older households. Many retirees are without compulsory superannuation although daily living costs have risen substantially. As additional workers in the 'baby boom' generation retire and less tax will be paid to the government, it appears there will be increasing pressure placed on the pension system. A large proportion of the population may struggle to enjoy a fulfilling retirement and be drawn towards a reverse mortgage, which in turn may be misunderstood. With an increasing proportion of older residents leaving the workforce, the community would be adversely affected if this cohort required government financial assistance due to the misuse of home equity loans.Read moreRead less

China is Australia's second largest trading partner. This project will enable Australian policymakers and business partners to gain better understanding of China's macroeconomic performance between 2008 and 2030. Secondly, China is the second largest source of immigrants to Australia. Given that Australia's population is ageing and labour shortages are expected, Australia may benefit increasingly from the flow of Chinese immigrants. The project will provide Australian policymakers with detailed labour supply forecasts in China disaggregated by age, sex, sector and region that will enable them to develop targeted immigration policies and effectively harness the flow of Chinese emigrants to Australia.Read moreRead less
The individual, the family and the state: expectations, intergenerational obligations and constraints in providing for old age. Intergenerational equity is a principle underpinning policy debates around financing retirement and care in older age. Enhanced understanding of this cohort's expectations and obligations will assist in policy development around financing retirement and paying for care that takes account of this cohort's expectations and obligations. Further, exploring the expectations ....The individual, the family and the state: expectations, intergenerational obligations and constraints in providing for old age. Intergenerational equity is a principle underpinning policy debates around financing retirement and care in older age. Enhanced understanding of this cohort's expectations and obligations will assist in policy development around financing retirement and paying for care that takes account of this cohort's expectations and obligations. Further, exploring the expectations underpinning intergenerational exchanges from this cohort's perspective will assist in understanding the dynamics around these exchanges and lay the ground work for future research into factors that facilitate cross-generation family functioning.Read moreRead less
Living Alone in Australia Project (LAAP). This study investigates one aspect of the changing nature of Australia's social fabric. It asks whether the sharp rise in living alone reflects a breakdown in Australia's social fabric or simply marks a change in the way in which the fabric is woven. Living alone has important implications for social policy, service provision and housing. But before these implications are identified we need a much better understanding of who lives alone and what living ....Living Alone in Australia Project (LAAP). This study investigates one aspect of the changing nature of Australia's social fabric. It asks whether the sharp rise in living alone reflects a breakdown in Australia's social fabric or simply marks a change in the way in which the fabric is woven. Living alone has important implications for social policy, service provision and housing. But before these implications are identified we need a much better understanding of who lives alone and what living alone means for people in terms of their social ties. By understanding the causes and consequences of the increasing popularity of living alone the study will help identify those who are at ?risk? and thus assist with effective targeting of supports and interventions.Read moreRead less
Sex, parthenogenesis and adaptation: a novel laboratory 'natural selection' experiment testing the adaptive significance of sexual and asexual reproduction. One of the greatest challenges for evolutionary biology is explaining the widespread occurrence of sexual reproduction. Many theoretical models show some inherent benefits of sex, however these models make assumptions that little or no empirical data exists for. Using a novel phenomenon found in the parasitoid wasp genus Trichogramma, I will ....Sex, parthenogenesis and adaptation: a novel laboratory 'natural selection' experiment testing the adaptive significance of sexual and asexual reproduction. One of the greatest challenges for evolutionary biology is explaining the widespread occurrence of sexual reproduction. Many theoretical models show some inherent benefits of sex, however these models make assumptions that little or no empirical data exists for. Using a novel phenomenon found in the parasitoid wasp genus Trichogramma, I will investigate the adaptive significance of sexual and asexual reproduction in a laboratory natural selection experiment and therefore directly test the theory for the evolution and maintenance of sex. This will be the first such test in a higher organism.Read moreRead less
Diet influences the selective advantage of mitochondrial DNA mutations. This project aims to examine critical mechanisms that affect mitochondrial DNA variation within species. It aims to test the hypothesis that mitochondrial DNA haplotypes have the potential to be under nutritionally induced balancing selection as a consequence of cellular signalling and/or Adenosine triphosphate (ATP) production by mitochondria. Diet can vary both seasonally and geographically and is a key environmental param ....Diet influences the selective advantage of mitochondrial DNA mutations. This project aims to examine critical mechanisms that affect mitochondrial DNA variation within species. It aims to test the hypothesis that mitochondrial DNA haplotypes have the potential to be under nutritionally induced balancing selection as a consequence of cellular signalling and/or Adenosine triphosphate (ATP) production by mitochondria. Diet can vary both seasonally and geographically and is a key environmental parameter that influences the ability of a species to colonise new habitats. The project plans to characterise the functional links between specific mitochondrial DNA haplotypes, mitochondrial functions and organismal traits. The expected outcome is a more precise grasp of the processes influencing genetic variation within and among species, which would inform current issues in ecology and genetics.Read moreRead less
The evolution of parental care in leeches: costs and benefits in a clade of hermaphroditic, invertebrate ectotherms. Parental care is a basic element of reproduction in many species. Nearly everything we know about parental care comes from study of vertebrates, especially birds and mammals. Leech is synonymous with exploitation, but many of these annelid worms are devoted parents. Because they differ dramatically from most vertebrates, leeches present an excellent, but as yet unused, opportunity ....The evolution of parental care in leeches: costs and benefits in a clade of hermaphroditic, invertebrate ectotherms. Parental care is a basic element of reproduction in many species. Nearly everything we know about parental care comes from study of vertebrates, especially birds and mammals. Leech is synonymous with exploitation, but many of these annelid worms are devoted parents. Because they differ dramatically from most vertebrates, leeches present an excellent, but as yet unused, opportunity to test our theories and understanding of the evoluton of parental care. We will examine the evolution of degrees of care and sibling competition in leech families, and use molecular markers to better understand the genetic structure of populations of these invertebrates.Read moreRead less
Are natural clones specialists or generalists? Using a model system to test alternative hypotheses for the advantages of parthenogenesis. Parthenogenetic organisms are all-female and reproduce clonally. Through discovering why these unusual organisms are sometimes successful we can better understand the significance of genetic diversity and sex. The Australian arid zone is a ?hot-spot? for parthenogenesis, with at least five independent examples including a native grasshopper and one of its host ....Are natural clones specialists or generalists? Using a model system to test alternative hypotheses for the advantages of parthenogenesis. Parthenogenetic organisms are all-female and reproduce clonally. Through discovering why these unusual organisms are sometimes successful we can better understand the significance of genetic diversity and sex. The Australian arid zone is a ?hot-spot? for parthenogenesis, with at least five independent examples including a native grasshopper and one of its host plants. I will apply modern molecular tools and ecophysiological techniques to test the hypothesis that parthenogenesis is favoured in this grasshopper because it allows the fixation of locally adapted clones. This research will provide a unique insight into the selective forces operating in the arid zone, Australia's largest ecosystem.Read moreRead less
Hybridization, polyploidy and the evolution of parthenogenesis in the Australian desert. This project considers the ecology and evolution of Australian animals that reproduce by parthenogenesis, i.e. without sex. These animals have long fascinated evolutionary biologists for the clues they provide about the role of sex in evolution. The Australian desert is a hot-spot for parthenogenesis, providing a unique opportunity to study the ecological and evolutionary forces favouring the loss of sex. Ou ....Hybridization, polyploidy and the evolution of parthenogenesis in the Australian desert. This project considers the ecology and evolution of Australian animals that reproduce by parthenogenesis, i.e. without sex. These animals have long fascinated evolutionary biologists for the clues they provide about the role of sex in evolution. The Australian desert is a hot-spot for parthenogenesis, providing a unique opportunity to study the ecological and evolutionary forces favouring the loss of sex. Our research will exploit Australian cases of parthenogenesis to understand how genetic changes associated with the transition to parthenogenesis affect ecological success. This will significantly extend our understanding of both the role of sex in evolution, and of the evolutionary history of the Australian arid zone.Read moreRead less

Bushfire, age care and farming is Australia's today and tomorrow.
A key aspect in bushfire control is early detection of ignitions by spreading miniature low power sensors in a large potential area in an ad hoc fashion and localizing. Response to panic alarm buttons by retirees in a retirement village where they are free to walk around while their location is monitored in real time using a wireless tag they carry to transmit data relating to their physical health(i.e blood pressure, ECG etc). Locating live stocks roaming around in the dairy industry using sensory transmission used for monitoring their statues is vitals for the farmer for improving efficiency.
