Sponsor liability does not extend beyond Australia.
Where a 457 visa employee travels overseas
for private reasons their Sponsor is not liable for any medical
or hospital costs incurred outside Australia.
When traveling on business for their Sponsor
they are mostly covered under a corporate travel policy.
However most corporate travel policies are only valid for Permanent Residents. 457 visa employees are not covered by the majority of corporate travel policies.
The same warning applies to credit card cover
and both private and business travel policies purchased through
travel agents. These are only
valid for Permanent Residents and a 457 visa
employee will have claims rejected.
Also sponsors sending 457 visa employees overseas
on business have a duty of care to ensure that the workers
compensation law in their State, allows for cover of Third
Country Nationals.
