Some visas require sponsorship and some do not. Most temporary sponsored visas are liable to cancellation if the sponsor (whether a company, other organisation, or family member/partner) withdraws their sponsorship. Most permanent sponsored visas are not liable to cancellation after they are granted if the sponsor withdraws sponsorship. Sponsorship can be very expensive (in the case of contributory parent visas, it can cost over A$100,000 in fees and bonds to sponsor both parents). Likewise, sponsorship can be very cheap for some other sorts of visas. In each case it is important that the sponsor is aware of their obligations before accepting the commitment.
