Under 30k?

Looking for some recommendations for cars under 30k. What I’m looking for is basically - a hatch or a sedan - Automatic - 2020 onwards and less than 60k on the odometer - smooth driving experience - not really a car guy so wouldn’t want to buy a cheaper car and then modify it - good quality interior and features

Again, not a car guy so would really appreciate if you could use simple language. I get that the budget isn’t as much as the requirements are lol but try your best thanks! Location: South Australia

Edit: Did a carsales search and it’s come up with quite a few options out of which I’ve shortlisted Hyundai i30 N line, Polo GTI, Mazda 3 G25, Skoda Octavia 140TSI, Skoda Fabia monte carlo 150, Toyota corolla zr hybrid and camry ascent sport. Which one would you recommend? Is there any other I should be looking at?
