So I just checked and I can’t find the airport either. I tried the IACO code, finding it via coordinates and on the map using google maps for reference which should of got me to it but I can’t see anything. I did notice a load of airports in area with the name “wurigelebur airport” I tried noting all the codes and searching but there were too many. I stopped after doing 5 (WAYP, WAYH, WAYI, WAYQ, WAYM) as realised was getting nowhere. One of these may be the airport you are after as they fit the location right. This probably just adds confusion so sorry! Hope it was helpful at least.
