Crown Casino and the MCG will not allow Abdul Nacer Benbrika in their venues after the convicted terrorist was released from prison.
Benbrika walked free after nearly two decades behind bars with 30 strict conditions imposed on his release, including that he could not go within one kilometre of an airport or port.
A ban placed on Benbrika by Crown remains in place, while Melbourne Cricket Club CEO Stuart Fox confirmed he would be blocked from entering the ground.
"He won't be permitted in the stadium", he told reporters on Thursday.
"We take security so seriously here and anyone that would pose a threat or a risk to the MCG won't be allowed in.
"It's as simple as that."
The terrorist was convicted over plots to attack Melbourne landmarks including Crown Casino and the MCG on AFL grand final day.
A Victorian Supreme Court judge granted the Commonwealth's application for an extended supervision order on Tuesday to allow police to monitor and keep tabs on Benbrika after his release.
It is only the third time such an order has been imposed since laws passed in December 2021.
