NV and linkt toll

Hi I’m driving to Brisbane and Sydney next week for the first time with my NL car (SG Fleet). I never had a Linkt account and used to check the website after each trip and the pay. SG website mention commercial Linkt account but ATO says toll fee isn’t tax deductibe (which I am fine with).

My question is, should I just open an Linkt account, like all other (non NL) cars, or I need to contact SG fleet for the commercial account?

Thank you
