Surgical-only cover pays for private hospital treatment and surgery, helping you skip public waitlists. Comprehensive cover adds day-to-day extras like specialist consultations, diagnostic scans, and sometimes GP visits or dental/optical — useful if you want broader support, but noticeably pricier.
Why does age matter so much?
Health claims become statistically more likely as you age, so premiums rise steadily through your 40s, 50s and beyond. Joining younger and staying continuously covered can help avoid new-condition exclusions that may apply if you switch insurers or re-join after a gap later in life.

Yes, generally significantly — since most claims are for smaller amounts, a higher excess shifts more of the routine cost onto you and meaningfully lowers your ongoing premium.
