In the 1880s timber was the main industry in Blackwattle Bay. Timber shipped in included old forest cedar from the north coast and kauri and rimu from New Zealand. By 1908 there were 15 wharves around Blackwattle Bay, mostly occupied by timber merchants. Around this time more mangrove swamps were reclaimed to make Jubilee Park. The area maintained its mix of timber and manufacturing industries, elegant villas and slum areas through to the 1920s. View of timber bridge at Blackwattle Bay, Sydney, Australia.
