If you are located in a foreign country, and wishing to marry an Australian citizen, or a permanent resident, or an eligible New Zealand citizen, you can lodge a prospective marriage visa (Subclass 300) to get permanent residency in Australia.

Both you and your fiancé must meet a set of relationship criteria to apply for this temporary visa:
After getting a subclass 300 visa, you’ll have 9 months to get married and to lodge a spouse visa, i.e. subclass 820 visa.Source: Department of Home Affairs, Australia
The subclass 300 prospective marriage visa application must be submitted when you are in your native country, and outside Australia at the time of grant. The grant of visa subclass 300 will give you access to enter Australia to get married. You will be given 9 months to get married with your Australian partner.
The prospective marriage visa pathway is, therefore, a 3-stage process to permanent residence, comprising the following steps:
Step 1: You will lodge a prospective marriage subclass 300 visa application via online IimmiAccount, which, if approved, will permit you to travel to and live in Australia for a period of up to 9 months to get married with your Australian partner.
Step 2: Once you have successfully married your partner (within the 9-month visa period), you are then likely to lodge a combined application for an onshore partner visa subclass 820 and 801.
Step 3: Two years after the lodgment of your combined subclass 820/801 visa application, the Department will evaluate whether you remain to fulfil the requirements for a grant of the subclass 801 visa, with a positive application resulting in a grant of permanent residence in Australia.Source: Department of Home Affairs, Australia
The visa subclass 300 is not very easy to get because you are not married to your Australian partner. Therefore, you have to prove the validity of your relationship and confirmation of getting married after you reach Australia. Proving relationship is not easy if you don’t have sufficient documents like photos, social media activities, electronic communications, and other. your parents’ awareness about your relationship is also very important as immigration officer will investigate a number of things before issuing the visa.Source: Department of Home Affairs, Australia
