Oh wise teacher, what does this mean?

I like Australia most of the time, especially their weird slangs.

Today I learnt a new slang.

fair shake of the sauce bottle

It means:
1. Tried very hard to get you. OR
2. Done their best. OR
3. To be given a fair chance.

Come on you all, dun give me fair shake of the sauce bottle! I have done fair shake of the sauce bottle and you have got to give me the fair shake of the bottle here.

I hope this is how this slang used. -_-
