Melsa Park is a place-name in the old activity list. Township parks are how Bribie handles shade, toilets and a picnic without a QPWS booking.
Treat this as a public-landscape mention, then verify the current facilities on Moreton Bay City Council or a current map. We will not invent a playground inventory or a barbecue count.
Parks in the townships pair with beaches on the nearest shore. They are not recreation-area camps. Take your rubbish; the national park will also ask that of you, in firmer language.
