3 of JHAS' current Line Maintenance customers (foreign operators servicing multiple Aussie ports) have heard the reports of their situation, and to ensure their own operational integrity have requested draft proposals from other providers to handle their MX. If things don't pick up, these operators will probably jump ship anyway.
At MEL, JHAS provide line maintenance to Air NZ, Vietnam, United, Air Asia X, Shanghai Airlines (I think or might be Sichuan), Royal Brunei. I pretty sure there's a few others, possibly from China, but Cathay Pacific Eng have picked up most of the Chinese carriers I believe.
I can also think of several line maintenance providers who'll be licking their chops at the prospect of picking up some of those contracts, especially the ANZ one, due to the number of transits.
