My personal experience with Freelancer: I wasted my time and money in simple project (content/Article writing).
Project bidders:
People with no knowledge and has got good review (don't know how they got good reviews could be paid reviews!) and they bid lower price then negotiate the price with you and increase it. Do not deliver project on agreed time and they wont respond for your messages. Once delivered they wont give you time to review and nag you constantly to release the funds for the unworthy work they have delivered.
Freelance Accounts:
They are many hidden charges which they don't tell you subscribe with them, you have to figure it yourself by checkig the transaction history. Some of the hidden charges are.
Deposit fee ($. 30 Fixed +2.30 %)
Project Adding fee + 10% GST
Project deletion fee + 10% GST
If you got less than 30 AUD in your freelancer account then you can't withdraw funds! You are trapped. You have to transfer more funds to match the minimum 30$ so that they can again charge you Deposit fee ($. 30 Fixed +2.30 %).
My recommendation is use a different outsourcing platform! Do not waste your money and time!
