@Melissa2028. What does your lease say? If its a standard one, chances are sub letting is not permitted without the landlord's consent (most states). If you do reside in Snug, TAS, then go to www.tutas.gov.au where I found the following:
Sub-tenancies are permitted under the following two conditions:
1) the ‘head’ tenant(s) must occupy the premises and 2) the ‘head’
tenant(s) must get consent from the landlord/agent. The landlord/
agent must not unreasonably withhold consent. A Bill currently before
Parliament may change these conditions so check the Tenants' Union
website for updates. Sub-tenancies are not covered under the
Act but an agreement will be subject to general contract law.
Consequently most landlords would not permit them as they provide little if any statutory protections, insurance becomes void and they would need to sue you and/or your guests personally. So they would find plenty of reasons to decline your request.
