According to the financially-strapped Adelaide Zoo – the 5 year rescue plan was carefully considered.

It includes job cuts as part of efforts to improve the zoo’s performance.

Overall, the business plan allows for fewer staff, the sale of land and a review of Warrawong Sanctuary in the hills.

A working group will be set up to identify inefficiencies, reduce utility costs and explore investment opportunities.

Land will be sold at Monarto near Murray Bridge to reduce debt, Warrawong Sanctuary will face a review and the zoo's conservation programs will be scrutinised.

Those found not to be "core" activities face the axe.
