Unless you want AirAsia invading the domestic skies, I highly doubt it will.
If you're an airline of note/value overseas, why commit yourself when you can just set up an aussie carrier or buy in to one (e.g. VA). They have barely had a profitable year in almost 20 of existence. And they've tried regional flying constantly and often failed to come up with a positive result.
Considering the current cost of PER-BME, I can hope that relaxation of cabotage would promote SIN-BME-PER (and similar) flights. Perhaps MNL-DRW-PER would have been more useful if the domestic sector were able to have been sold.
