Talk to the neighbour first — most noise issues come from people who don't realise. If that doesn't work, report the breach in writing to the strata manager so it's documented, and ask the committee to issue a notice to comply.
If the breach continues, the owners corporation can apply to the state tribunal for orders and penalties. Genuine excessive or persistent noise is also a matter for police and council in some cases — strata enforcement and council enforcement can run in parallel.
