Indian Passport nearing 6 months validity, Will it be a problem to travel to Australia without its renewal though a Valid 2yrs Visa is available

Passport expiring on 15th Dec 2019. Hold a WPLT for 2 years. Planning to travel Australia around 6th Jun 2019. Is there any 6 months restrictions on Indian passport in Australia, Will it be causing any issue with Immigration Services both during checks in India or Australia. Would like to get honest suggestion in this regards, Should I get my Passport renewed before travel only?
