Penalties apply to tourists who breach this 'no work' condition. The type of visa you will need depends on how long you wish to stay in Australia and what you want to do during your stay. An ETA is an electronically stored authority to travel to Australia for a short stay and no visa label is placed in the passport. ETAs are available from participating travel agencies when making travel arrangements, or though participating airlines, as well as at Australia visa offices overseas. Note that holders of Taiwan passports can only be processed for an ETa if resident in and applying in Taiwan.
ETAs are available for tourism and short stay business purposes.
Tourist ETAs and short validity, single entry business ETAs, are free of any Government charge. There is a charge for long validity business entry ETAs. If you do not hold a passport approved for ETA, you will need to apply for a 'label' visa. There are two main types of short stay 'label' visas. Tourist visas - usually provide for a stay of up to 3 months on each visit.
