Gee, I've never seen so many people who haven't got a clue offering so much advice.... Black & Gold Macaws... Hacintha (???) Macaws being cheap... red & green Macaws cheaper than Blue & Golds... What a huge lot of crappy advice...
Legal imports of macaws and some other species were allowed from the UK (only) in the 1990s, and because the quarantine for birds operated on an 'all in, all out' basis, it was only economical to bring in many birds at once because the facility at Spotswood in Vic was tied up totally until that shipment was cleared (45 days). The three large species allowed in were Scarlets, Greenwings and Blue & Golds. Hyacinths have never been legally imported, although there are a few around, and they are VERY expensive.
The large red Macaws (Greenwing, Scarlet) are currently in very short supply, and often command around $15k each as weaned babies, Blue & Golds are cheaper because they are generally easier to breed. You might get one from around $4k, but high quality birds from legit bloodlines still fetch around $7k. This would include a full vet workup at around $450 including bloodwork. As with anything, you get what you are prepared to pay for. Very cheap birds are often poorly fed during raising, and come from breeding stock which reflects poor nutrition. You could be buying a heap of trouble.
You do not need a licence in NSW for Macaws, but you do in WA. In WA you need an import permit to bring a Macaw into the state, but you don't need an export permit to send one out! Go figure! If you import a Macaw into WA, it must be photographed at the airport before it is released to you, the photos are emailed to DEC to verify that it's not an African Grey in disguise (AGs are illegal in WA), and the Ag Dept officer is advised that your B&G Macaw is actually a B&G Macaw by DEC, and away you go...
What a load of bollocks...
