Work has started on building a new Australasian zone at Tilgate Nature Centre in Crawley.
Keen-eyed visitors have already noticed some changes with more outbuildings, avaries and paddocks being put up.
The new zone is due to officially open on April 2.
Bouncy new parma wallabies and pink galahs - a type of cockatoo - have been exploring their surroundings as they wait for their new enclosures to be finished so they can move in.
Meanwhile, Shelia the emu and some red-neck wallabies are making themselves at home with the ducks down by the lake.
Shelia is said to be very friendly and will even eat crickets out of the hands of her keepers.
She is also nosey and enjoys watching the builders as they get to work on the new enclosures.
Shelia is soon to be joined by some other emus who are moving from Wales to the nature centre.
Shelia and the wallabies will also be joined by some more animals when the new enclosures are finished.
Details about Australia’s most dangerous, its weirdest and most wonderful animals will be displayed throughout the new zone, along with wooden sculptures of the continent’s most famous animals.
