With an increase in council revenues, Mack reinvested the funds in a public works program into several new and renovated parks, car parks, childcare facilities, community and sports centres, and major extensions and renovations to the Stanton Library and North Sydney Oval. Infrastructure also took on a distinct local identity, with Council investment on new street signs, bus shelters, colour schemes of public buildings, paving and street furniture. In 1982, council voted to popularly elect the mayor, with Mack being directly elected twice to the position in 1983 and 1987 before retiring in 1988.
