Luggage point has been the butt of jokes for its past history as
the site of the “nightsoil” disposal depot for Brisbane. It was
replaced with what was Australia’s most modern Sewage Treat-
ment Plant which came online in 1979.
Just recently the largest tourist ship to visit Brisbane tied up
directly across the river at Fisherman Island which was once
a mangrove island but is now a port/wharfage area and the site
of the largest landfill of seabed in Australia.
Luggage Point is at Myrtletown and is at the mouth of Boggy
Creek, the Brisbane River and Bulwer Island. The area still has
one farm but is rapidly being developed as the “Tradecoast”
commercial area but a lot of the mangrove forests and swamps
along the creek and river still remain.
Myrtletown has a riverfront picnic area which once boasted two
boat hires and also has two carefully preserved concrete air raid
/gun emplacements; some of many that were built in 1942 in
this area to protect the Eagle Farm Airfield from Japanese at-
tack. The treatment plant is adjacent but not open for inspection.
This forgotten area is worth a visit. The picnic area is UBD
