 For some years the Cairns Town Council continued to transport quarry material from Edge Hill to Cairns via its own tramway, using the former railway alignment, but this was abandoned by 1923.In 1940 about 10 acres (4 hectares) at Mt Islay, above the recreation reserve, again was gazetted as a municipal quarry, this time for land reclamation purposes.The base of Mt Islay lay within the recreation reserve and from 1940 the slope adjoining the gazetted quarry was excavated as part of the quarry workings.
