Weddings in Melb/ Victoria are so expensive! Help (please)

I’m heartbroken because it’s looking like we won’t be able to afford the wedding we want, despite having the venue booked for two years. Even then, we’re keeping it simple (choosing fake flowers, going budget on photographer/ videographer etc). Can anyone recommend a cheaper venue? We even thought of a micro wedding at one point. An elopement would kill my parents and in turn me. Currently we’re thinking of a ceremony somewhere and then a bar/restaurant for the reception. To give you an idea, my partner is very woodsy castle glamour (our ceremony venue is that) and I’m a city girl (want the reception to be like that). Thank you!
