Now an eclectic, artistic hub, the seaside port of Fremantle has come a long way from its convict outpost days. Greig discovers the waves of migrants who've added a splash of colour to the city; including 10-pound poms, Italian migrants and boatloads of young women who arrived on 'bride ships'. He explores the roots of Fremantle local and ACDC legend Bon Scott, and learns about the Rajneeshees - an obscure religious cult that painted the city orange.
