Twins Research Australia COVID-19 Study

We thank our amazing researchers and TRA members who make our COVID-19 research possible. Called TRACKERR, the Twins Research Australia COVID-19 Knowledge, Experience, Reaction and Resilience project is a series of ongoing studies that are investigating the pandemic’s short, medium and long-term impacts on Australian families.

This study involves a series of online surveys, the first of which was launched in April 2020 with further surveys expected every 6-12 months.
