The breeding pair, which it is hoped will produce a Joey next year, will also be officially named at the open day after an online appeal for suggestions.
Animal Care Trainer Jonathan Taylor said: "The Animal Unit open days last year raised the money for us to be able to create the enclosure and the Wallabies have settled in well in a very short space of time.
"They are very placid and social creatures and the public will really enjoy seeing them for the first time this Sunday."
Animal Care student Chelsea Oates (17) is among the student body who have helped to fund raise and build the enclosure - complete with a shed and a wind break to shield them from the elements.
She said: "The male is very happy to come up and eat food out of our hands but the female is still a bit more wary.
"They love nothing more than stretching out to enjoy the winter sunshine and appear to be very happy in their new surroundings.
"We are all looking forward to learning more about them and how to look after them as part of our study programme.
"They are beautiful animals and we are really hoping that they have a baby in the Spring."
The open day on Sunday December 10 will be held between 10am and 4pm.
Youngsters will be able to join students and staff to feed the meerkats, goats and alpacas. There will also be the opportunity to get hands on and handle some of the animals.
There are lots of other activities for visitors to join in such as craft making activities, animal enrichment tasks, raffle and tombola, charity stalls and keeper talks. The Plant Centre will also be selling a wide range of Christmas trees.
