NRMA raising the cost of EV charging

I received an email this morning advising that NRMA will be increasing the cost of charging from 60c/kWh to 66c/kWh for chargers capable of up to "150kWh" ie 150kW.

For chargers that deliver 175kW or higher, the rate will rise from 65 to 71c/kWh.

The 10% member discount will still apply. I wonder if that means 66c/kWh with discount will be rounded up to 60c or down to 59c?

Is NRMA considering installing PV arrays at charger sites to keep costs down, perhaps as roofing as a sorely needed weather protection/shade upgrade at the many current bleak exposed* sites?

*most other company's charging sites are like that too
