Fuel stocks and hidden bases sustained eastern operations

Did secret refueling bases from the Singapore strategy help the Royal Navy?

Yes. Fuel stocks in Ceylon and Australia were critical, and they meant eastern fleets were not constantly close to running out of fuel.

Fuel reserves and concealed support arrangements gave the eastern fleets endurance. Ceylon and Australia held large stocks supporting both British and American operations across Southeast Asia, the Indian Ocean, and the Pacific. Forward deliveries still mattered, while the fleets had enough reserve depth to avoid living from one shipment to the next. A temporary disruption or operational surge was therefore less likely to immobilize them immediately.
