如果你是坡籍　可以申请长期居留签证。In recognition of the close ties between Singapore and Australia, Singapore nationals will benefit from a new long validity, multiple-entry option for the Visitor visa (subclass 600) for Australia. The long validity visa option is available for the Tourist stream and the Business Visitor stream of the Visitor visa. 感觉坡护照还是蛮有含金量的
