Their original brewhouse was at their pub diagonally opposite Manly Ferry Wharf and I had a good session or three there over the years, then they moved to Brookvale on the North Shore in the commercial Bob Jane T Mart, panelbeaters etc. area there. I'd expect that their draught production is now the major part of that brewery's production. However their bottled pint and six pack offering is widely available around the state and no doubt Australia as a whole, and I can't see the Brookvale operation having enough capacity to satisfy the whole state and national market so clearly they are putting these beers through contract brewing.
Maybe a bit like James Squire that is mostly now produced at Toohey's Lidcombe. I hope the beers don't go down the same track as JS.
I'd be interested to know what brewery LC saw the 4 Pines run going through but of course that would be commercial in confidence. Maybe one could speculate that it could be near a famous pie joint, perhaps.
