If your friend really knows of such hulks remaining from his explorations and involvement in the Warbird movement he probably also knows what the legal situations are, and what the recovery options are in terms of the advice you are seeking in anycase.
I would have to agree with JDK thats there are plenty of existing projects and volunteer museum collections to lend a hand to, and would question how many substantial wrecks really remain in Australia "awaiting recovery", there are many many crash sites, and at least the 300 you refer to, but most do not retain much structure of rebuild value having been subject to crash recovery during the war, or significant impact destruction in the first place, or deterioration from souvenir hunters, scrappies, bush fires and the elements, and certainly few have sufficient remains on site to yield a restorable hulk, other than an identity for "data plate" reproductions?
Having said that Victoria's ongoing drought in recent years has exposed a near complete wartime Wirraway ditched in an inland (salt) lake, despite being apparantly "intact" I am not sure of its integrity to survive removal or restoration or display "as is" and am unware of the current future planned for it.
The laws covering aircraft wrecks in Australia are largely State based Heritage laws unless the crash is on Commonwealth land or in the sea, in which case Commonwealth Heritage Law will prevail, (In some case both Commonwealth and State Heritage Laws may prevail depending on the wrecks significance and source).

Fatality Wrecks may also be subject to Veterans Affairs and War Graves
protection.
Export of wrecks or complete historic aircraft is governed by the Federal
Moveable Cultural Heritage Act.

WA, QLD, NT, NSW and Victoria are all active in protecting known aircraft
wrecks with investigations in the past regarding attempted recoveries of
aircraft from Lake Victoria NSW, Darwin surrounds, and Lakes Entrance (an infamous theft of the major parts of P40 in a swamp "during" an official RAAF recovery, and using the RAAF recovery equipment??? )

The Northern Territory currently has 232 listed shipwrecks and 73
listed aircraft wrecks (lost at sea), the majority of which have yet to be
located. Information relating to these wrecks can be found on the Museum and
Art Gallery of the Northern Territory�s Shipwreck database.
examples of this legislation being in place is shown in relation to the
recent discovery of an intact WW2 RAAF Wirraway in a lake in Victoria.

Lake Corangamite plane crash: A crashed World War II RAAF Wirraway
aircraft was discovered in early Junein Lake Corangamite, near Colac,
Victoria. Heritage Victoria protects all aircraft crash sites over 50
years old as historic archaeological sites, and the RAAF has been briefed on
the find. The site was recently exposed by receding water levels in the
Lake and reported by Parks Victoria officers to Heritage Victoria. The site
appears intact and remains mostly submerged. This plane is believed to be an
RAAF Wirraway Serial No. A20-405 that is recorded as having crashed into
Lake Corangamite, 400 metres from shore on 17 March 1943. There were at
least 355 military aircraft crashes recorded in Victoria during World War
II, most of them the result of training incidents. Wirraways were the first
aircraft to be mass manufactured in Australia, and this eighteen years
before the first mass manufactured Australian car. Between 1939 and 1946 the
Commonwealth Aircraft Corporation (CAC) produced 755 Wirraways for use as a
general purpose trainer, though they saw action in the desperate defence of
Malaya and Papua New Guinea where they were lost at an appalling rate to
superior Japanese MitMalaya and Papua New Guinea where they were lost at an
appalling rate to superior Japanese Mitsubishi Zero fighters. Only eight
Wirraways are still in existence as restored or partly restored historic
aircraft
There are many known wreck sites surviving in Australia with visible
aircraft remains, but these individual wreck sites are well short of the
components required to constitute a "recovery" and at best most would only provide some parts for pattern or components, rather than sufficient remains for a full restoration.
There is a famous 30 page A3 print out of RAAF co-ordinates of WW2 crash sites that every man and his dog copied during the 1980s and which has been scanned and uploaded onto the web, although even more elaborate websites with lists have since been developed.
