Rent across the combined capitals has reaccelerated in March compared to the previous quarter, according to the Domain March Rental Report.
Despite this, it was the slowest March quarter increase in four years.
Out of all the capital cities, Darwin saw the largest increase year on year for houses, with a 7.7% rise. The city has also become the second most expensive capital city to rent in, tying with Canberra and just trailing behind Syndey.
The median price for renting a house in Darwin has reached a brand-new high of A$700.
Dr Nicola Powell told ABC News that the increase in rental prices in Darwin is likely due to a “mismatch in demand and supply”.
"When you have a vacancy rate below 2% it shows that it is a landlord's market and we've got to remember that Darwin's vacancy rate is sitting at 0.6 per cent," Dr Powell said.
Annual growth for the rental price of houses has slowed to its lowest point in nearly five years for Sydney and Perth, just over four years in Brisbane and Adelaide and just over three years in Melbourne.
Hobart was the capital city with the lowest median house rental price, with the price growing 3.6% year-on-year.
As for unit rental prices, it has slowed to its lowest point in 3.5 years in Brisbane, around three years in Syndey, Melbourne and Adelaide and 2.5 years in Perth.
