Some residents of one of Sydney’s richest suburbs are railing against the NSW government’s proposed housing affordability reforms.

Judith, 89, is leading the charge and taking the Minns government to court over its push to add 500 extra homes in Mosman, in Sydney’s affluent Lower North Shore.

The group has even hired Allan Johnston, one of Australia’s best jingle writers, to compose a protest power ballad. Johnston was behind the famous I feel like a Tooheys song and the iconic C’mon, Aussie, c’mon cricket anthem.
