The work is part of the Blackbutt Reserve Plan of Management, drawn up in 2012 and one of four priority projects yet to be completed across Newcastle.

A Newcastle City Council spokeswoman said the work, to be completed in the Carnley Avenue recreation area, would start some time after April.

Tender applicants will be considered at the council meeting this month.

"Site preparation commenced in March and work is scheduled for completion in September, 2014, weather permitting," she said.

"This wildlife arena will be constructed within the wildlife exhibit, giving visitors an opportunity to get up close with Blackbutt's animals.

"The existing amenities building will be replaced with a larger facility to better meet the needs of visitors.

"Blackbutt Reserve is a unique environment with a diverse range of habitats and ecosystems and we will be working to ensure this is conserved throughout the project."

The reserve will remain open for the duration of the work, but visitor safety will be ensured.
