Ocean surface water temperatures are up due to AGW.
All of these factors in concert will add to precipitation when atmospheric conditions are favourable.
Many NSW locations have experienced record flood events. Lismore has faced three devastating floods in three years. Upper Clarence flood levels broke all records.
By all means pretend that nothing unusual is happening if it makes you feel better but you will still be wrong. We are living with AGW and we have caused it. Pretending otherwise will not change that reality.
