Hoppy Halloween! 🐰
Don’t let Beatrix Potter’s delightful tales of Peter, Flopsy, Mopsy and Cotton-tail deceive you, rabbits have become one of Australia’s most widespread and damaging invasive species.
Since being introduced to Australia in 1859 by pastoralist Thomas Austin, who thought they’d do “little harm”, rabbits have multiplied rapidly and caused destruction in their wake.
Today, rabbit populations are estimated at around 200 million, vastly lower than a century ago due to the introduction of biocontrols, such as the Myxoma virus and Rabbit Haemorrhagic Disease Virus.
While rabbit viruses work very well for a time, rabbits overtime develop resistance to viruses.
Our scientists are developing a new way of growing the rabbit virus, calicivirus, in the lab to speed up selection of new variants with potential to boost control.
We're also tracking virus strains circulating in Australia to map the activity of the various rabbit biocontrol viruses and have begun investigating longer-term solutions such as genetic biocontrol (commonly known as gene drives).
