Parramatta is the one place in this group where the travel question is real. The acts at the top of the list are pinned in the city centre, and that's a genuine drive out the M4 or along Parramatta Road, not a five-minute hop like the inner west pages. On a Saturday afternoon in December it's a slow one, and an act quoting a late finish is quoting the drive home too.
None of that means you should look elsewhere, because Parramatta has the rooms the inner city doesn't: hotel ballrooms, big club function spaces, conference floors and a corporate calendar of its own. Those are band and DJ jobs with real capacity, and a fair number of acts do give the area as their base. Just ask each one where they're coming from before you compare two quotes, because that answer is doing more work here than anywhere else in Sydney.
Top picks are the nearby performers with the most visible reviews, then rating, then the closest; further afield the closest come first, and premium listings break remaining ties. Distances are straight-line from Parramatta. Ask each act whether they travel to your venue and what that costs.
Some do and it's not unreasonable, because it's a genuine run each way and the return trip happens after midnight. Acts based in western Sydney won't, and they're on the full list further down. The fair approach is to get a quote from one of each and see whether the difference is really about the road or about the act.
A band with a full system, or a DJ who works rooms that size, because a large ballroom needs more than a duo can produce. Give the act the guest number, the ceiling height if you know it and whether the venue has house sound, since all three change what they bring. Many of these rooms also want background music during dinner, which is a separate booking or a separate set.
This page is already the Sydney pool, just measured from Parramatta, so searching the city won't add names you can't see. What it will do is add distance to every quote. Start with the acts on this list that are genuinely based out west, then widen only if the format you want isn't here.
An act based out west treats Parramatta as a local job and one from the eastern suburbs does not. It rarely changes the price outright, but it changes how early they arrive and how willing they are to add a set at the end.
A ballroom or a large club room will swallow a duo. If you're filling a space with hundreds of people, you want a band with a proper system or a DJ with a rig built for the size, and the act should be asking you the guest number before they quote.
Parramatta's business calendar competes with the city for the same end-of-year Fridays, and the acts serve both. If your event is in that window, book earlier than you think you need to.
