is Indiegogo like Kickstarter when no money is taken unless the project is successful in raising the $7k.

Kickstarter is only available to residents of the USA and the UK

Indiegogo is available to Australians and a project can be run one of two ways. Either an "all or nothing" fundraiser (same as KS) or another way where ALL money raised - even if it is only 10% - you get.

It depends on what you are doing with the money and project how you would work it.

Remember, you are NOT buying anything, you are pledging your support for a project by helping people get their ideas up - 'perks' are offered but not a given....and often are never delivered.
