Canberra rents have fallen by almost half a per cent over the three months to June, according to new research from Corelogic.
The change in rents across all properties in the territory fell by 0.4 per cent, in line with a national fall of 0.5 per cent.
But the estimated median asking rent - this only takes into consideration the value of an average property in the territory - dropped 1.7 per cent.
The estimated median asking rent in Canberra is $566, only $2 less than Sydney at $568. The median rent in the harbour city dropped 1.6 per cent.
Sydney's rent for the total value of all properties dropped 1.3 per cent over the quarter.
Corelogic head of research Australia Eliza Owen said the Canberra market had showed more resilience than Sydney.
"If we look at the rental market when we measure a change in rent across the capital city we tend to look at a whole market and not just a median," she said.
"That's where we see a bit more resilience across the whole Canberra market."
Ms Owen said the higher end of the market in Canberra was more stable than Sydney.
"The higher end and the lower end [of Sydney's market] have been more vulnerable to some of the demand shocks brought about by COVID-19 relative to the ACT," she said.
"[Canberra] has a lower exposure to things like vulnerable workforce sectors and international migration.
"That's helped to keep stability across the higher end of the Canberra rental market."
Broken down to dwelling types, the estimated median asking rents for houses in Canberra was $601 a week and for units it was $485.
