We assume 70 percent of your drawn roof area is usable after edge setbacks and access, 470W panels at roughly 2 square metres each, average Northern NSW generation of 4.2kWh per kW per day across the year, and a power rate of 32c per kWh. The battery suggestion covers about 60 percent of your daily usage, which is a typical evening share. Every real system is designed from your actual roof, switchboard and usage pattern, so treat this as a conversation starter, not a quote.
