Here's a bit from the Subtropical Banana Growers' Handbook put out by the Queensland Government:

"In Queensland, the Plant Protection Act 1989 limits the growing of
bananas in home gardens. Note that Cavendish bananas are not
permitted. Residential plantings are limited to a maximum of 10 plants
with a maximum of 30 stems but you must have an inspector’s approval.
The varieties you are permitted to grow in a residential block are also
restricted. Permitted varieties are listed in the table below.

In New South Wales, there are no restrictions on numbers of plants that
can be grown in home gardens and Giant Cavendish types are approved
with a permit.
