Or worry that the oil pressure is actually low.
I would get the NRMA/RACQ or whoever to have a look before driving it anywhere, just in case.
How frequently is the light activating for?

 

If it's the oil pressure lamp, then that is different to the oil level (although both are mostly related - level below the min = higher temps = lower pressure). With a sufficient oil level, the car could still have pressure issues, such as a malfunctioning pump, although oil pumps should outlast the engine.

I had the low oil pressure lamp not too long ago. Turns out it was simply the sensor, but the sensor had failed in a way to cause an oil leak, potentially a catastrophic leak had I kept driving much more. A sensor is cheap, it's worth booking it in.
