I'm not (yet) confident that Lion Air will even fly in Australia...
I'm also yet to totally understand SkyAirWorld either and their strategy. On the one hand they're operating their own RPT services to Honiara, then they're wet/damp leasing to others such as Air Nuigini. Plus the odd charter. Then they're chasing (reportedly) mining contracts and finally looking at doing the Lion Air deal!
Their future fleet is a bit of mixed bag as well - E170, E190, E145s (any news on these and where they'll go?) and of course the joint-venture Lion Air 739ERs!
