Online business coaching can be cheaper than in-person, but that's not a rule. Most business coaches are okay traveling for their clients. However, they might charge a lower rate if they feel like it'll be less of a hassle for them to do it online. 

With that said, it's also pretty hard to get an exact number on business coaches because I've seen them charge a wide range of prices depending on what they do and how they do it. On average, most Aussie online coaches charge between $100 to $300 AUD per hour on coaching. 

Though the average rests between $100 to $300, the full range of prices I've personally seen runs from $50 to upwards of $1000 per hour. When hiring a business coach, I suggest you ask the following things:

• Do you have any specializations that I should be aware of?
• What is your experience as a business coach? Did you have a business of your own in a field similar to mine?
• Do you offer an introductory discount?
