Hiya @FinanceSarah,
If an entity is collecting GST it has to be registered. The GST portion of the payment being received is intended to be passed on to the ATO. The sole trader would need to back date a GST registration to the first time they were paid GST and forward on all of the amounts collected to the ATO. Alternatively, it can be paid back to the banks, and no longer collected. As the sole trader should not be collecting GST in the first place.
In short, they don't have to register, but if they don't they need to pay the GST back to the banks that paid it to them in the first place.
