I’m not sure when the webinar is, as I am not a pro member, but choosing a drone is much like choosing a camera – there is one for every price bracket and for every quality. And just like cameras, there is no point in buying one that is much more expensive than what you need. I think there are probably two things to look into: the laws and your needs.
The laws are different in every country – I am only familiar with Canadian drone laws, but I would suggest looking at the CASA website for a starter: https://www.casa.gov.au/aircraft/landing-page/flying-drones-australia I am guessing that if you are thinking of getting a drone specifically for photography that you are wanting to use it to add value to some business or ministry. If so, that is commercial usage.
If you look at your needs and find that a drone is part of those needs, there are two options: do it yourself and get the tools and qualifications necessary or hire someone to do the part that you won’t do.
