The ban on the ban on rental evictions and price increases amid the COVID-19 pandemic has been extended until December.
State Treasurer Tim Pallas said the current ban on evictions and rental increases, due to expire on September 29, will now be in effect until December 31.
"Nobody should be worried about losing a roof over their head," Mr Pallas said.
The Property Council of Australia Victorian executive director Cressida Wall said the extension will "push many landlords to their limits and beyond."
"Landlords cannot keep propping up the system," Ms Wall said.
"As the crisis goes on, we will need goodwill and action from both banks and governments to ensure that these businesses do not go under and take the economy down with them."
Council to Homeless Persons chief executive Jenny Smith said the extension was a relief to renters doing it tough during the pandemic.
"This is a time when the importance of having a safe home has never been clearer," Ms Smith.
The Treasurer announced further support for residential and commercial landlords, including further land tax discounts from 25 per cent to 50 per cent.
A fund of $60 million, via a financial hardship scheme, is also available for small commercial landlords, which will provide up to $3000 per tenancy.
