It is essentially a commuter town for people working either at the Aluminium Refinery in Pinjarra , in the heavy industry at Kwinana , or workers prepared to make the daily trek north to Perth . Further , Microsoft was negotiating with Bristol into August to reach a new contract . Heading uphill from the Trading Post Cafe , there are several fine homes and landscaped gardens . Gormley persuaded the local people to strip naked . The Hanging Rock Picnic Cafe , at the base of the rock , sells Devonshire teas , lunches , local crafts and souvenirs . Grand Ridge brewery ( previously known as the Strzelecki brewery ) was created out of the redevelopment of the Mirboo North Butter Factory . The combination in the 1950s of an increase in tourism ( especially day trippers from Perth ) and the development of Kwinana as a major industrial centre , saw Mandurah grow rapidly . In late spring , the purple and gold Mirboo Lily , the town 's floral emblem , blooms at the reserve and and in the general area . The Mt Eliza Fair is held on the Melbourne Cup holiday and the Toorak College Fine Art Exhibition in August . Today , Mirboo North is a small settlement which relies upon dairying , and the cultivation of potatoes , maize and onions .
