I've had a wander through the Pikitia Press site. There's a lot of Australian and New Zealand material, but only a few full comics, most of which are already on Comic Book Plus (like stories from Jet Fury 15 & 17, Devil Doone 26, Crimson Comet 10) - and two stories identified as being from Sea Battles Giant Comic, identified as being by Virgil Reilly, which I confirmed from info in the AusReprints site (which is currently erratic - James Zanotto is working on getting it functional again), including the original publication issue.
Paw - it's possible that True Navy Combat may be listed as just Navy Combat. There was a comic series called Comics Library, for most of its run circulated between three second-level titles: Navy Combat, Warfront and Fighting Fronts. Navy Combat was original Aussie content, the other two US reprints. It appears they added True to Navy Combat when they rebooted it as a new series.
What might be useful is to develop a list of online and hardcopy sources of information on Australian and New Zealand comics for those looking into these two comics environments that have a fair amount of crossover of creators, titles, and so on. There are links off to the US (mostly coming in, but Kazanda is by a NZ artist, published in Australia, and re-edited and published in the US); the UK; and Brazil (with some Frew comics republished and extra stories added in Brazil).
I'll have an initial go in the next couple of days, which people can add to.
