re #8. Hi Arthur, I was Project Manager on the Gold Coast Sewerage Scheme 1966-69. The tallest building on the Coast then was 6 storeys high, and we spent an emergency saving it from erosion. The old wooden bridge from Spit to Southport was still in service at first. I then inherited the new concrete bridge general foreman - another Scotsman - as my much-needed GF on the sewerage. I think the Coast has grown up since then - literally.
