AustralianSuper Pty Ltd and Colonial First State Investments Limited have put the two airports up for sale with expectations above $195 million.
The two sites, which generate an annual rental income of more than $20 million, span 509 hectares in total, with the potential for more than 40 hectares of surplus development land.
Interested parties are being asked to submit non-binding indicative offers after which a shortlist of potential buyers will most likely be drawn up to undertake detailed due diligence before making a final offer.
The two airports were purchased as part of a package along with Hoxton Park airport in November 2003 for $211 million.
In total across both Bankstown and Camden there are more than 175 tenants, half of which are related to the aviation industry.
Bankstown, the fifth busiest airport in Australia, makes up the bulk of the revenue.
Several expansion projects are in the works for some existing tenants. In addition to that there is 12.7 hectares of surplus land on the site currently and potential for a further 19 hectares.
Camden has a little over eight hectares of surplus development land.
The Hoxton Park airport is owned by Mirvac which is developing it into a logistics and warehousing centre for the Sydney area.
