"...they get a GST Concession, Income Tax Exemption and an FBT Exemption.."

Every ABN holder gets a GST Concession, regardless of whether they are a charity, not for profit or a commercial entity. That is what the BAS Report is for. Only the final consumer pays the GST.
Income Tax Exemption - Not for Profit or Charity.
FBT Exemption is available for certain industries - Health industry is one.

A not for profit can be required to pay tax on income not derived from it's core charitable pursuit.
