Dropping an accurate technology until end of season

After a forced break of four months, this sport has returned in Australia last Friday, but with a slightly different rules than usual. One of them (and the biggest) is that the A-league have suspended the video assistant referee system for the rest of the season. This decision was explained by the football president as an unavailability for the audio sound to reach spectators on stadia. Many other mandatory protocols were altered before the kick off (such as handshaking, toss of coin, clubs and referees are entering the pitch from separate entries).
Regular season in the country finishes on 19 August, then comes semi finals, while 11 nights later is the final duel.
