The last exposure site listed by the health department was Body Fit Training in Altona North.
Anyone who visited the tier-2 exposure site on Wednesday between 5.20am and 7am needs to get tested and isolate until they receive a negative result, after a person with COVID-19 attended the venue.
Chief Health Officer Brett Sutton declared 11 local government areas in Queensland red zones at 8pm on Saturday night, after large parts of south-east Queensland entered lockdown yesterday.
Anyone entering Victoria from the red zones is required to get a permit, get tested for COVID-19 immediately and quarantine for 14 days.
Non-Victorian residents who have been in a red zone since it came into effect cannot enter Victoria without an exemption.
The affected areas are City of Brisbane, Moreton Bay Regional Council, City of Gold Coast, City of Ipswich, Lockyer Valley Regional Council, Logan City, Noosa Shire Council, Redland City, Scenic Rim Regional Council, Somerset Regional Council and Sunshine Coast Regional Council.
Victorian health authorities are now asking more than 5000 orange zone arrivals from Queensland over the last two weeks to get COVID tested again following increasing risks from the state.
Chief Health Officer Brett Sutton said the health department will be following up with people who returned from south-east Queensland to complete a second test seven days after their first because there has been a longer period of risk in south-east Queensland.
Thats up to them as orange zone arrivals but it will give us greater confidence, and help protect the Victorian community.
As a result of the Queensland lockdowns, AFL players had to scramble to Victoria, with three games rescheduled to take place in Melbourne on Sunday.

Of the four new cases reported on Sunday, two are household contacts of a confirmed case connected to the Ms Frankie cafe, one case is a known social contact of a person connected to the Young and Jackson pub outbreak, and another is a contact of a positive case who attended the Wallabies rugby game at AAMI Park.
