cert 3 in landscaping construction Queensland

Hey I currently have a lawn mowing/ hedge trimming business, looking to expand into more turfing and other landscaping jobs. was made aware I need a license, and I may need this cert to get the license. any landscapers here that can simplify the process for me? can you do this coarse at tafe or online? or do you need to be employed by a licensed landscaper? How did anyone get their license if you need to be working with someone with a license to get the license? that doesn't make alot of sense.
