What the engine says about Marmion
Demand 6/10: an affluent, family-oriented coastal suburb (2,390 residents; highest family-household share of its belt at 80.6%; lowest rental at 10.6%) anchored by the long-standing Marmion Angling & Aquatic Club and its beach — quiet and almost entirely residential, leaning on Sorrento and Duncraig for shops.

Competition 4/10: a small beach-and-club-adjacent destination format can work on the foreshore and weekend traffic, but most everyday spend leaks to the neighbours.
