Best bet would be to call Immigration
They will advise them if a return ticket is needed or not
Even though a visa is granted , once they arrive in Australia Immigration may question whether they have a return ticket or not & why not etc
Possession of a visa also does not guarantee entry into Australia
It's up to Immigration on arrival to decide if all is ok
If there is any problem they can then refer to what they were addvised from the Immigration Dept before arrival
