Confusing sign

Brisbane-confusing signs everywhere
Two examples-and thank %&$#@t I used to live there. Robertson Rd Sunnybank downhill looking for entrance to freeway south to Gold Coast-now I may be old and silly but I ended up in the f&%^*in bus depot twice and thru the radar once. Since I departed Oz some time ago and in a hire car (reverse convict) still trying to pay the f%#@&ng fine-not my department etc etc. I expect to maybe be arrested next time I front the airport-something some of old timers can surely relate to, for different reasons!!!
Example 2-driving to airport past The Cauldron (Lang Park for all u Mexicans) -SWMBO says go left BF sign says go right thank XXXX I could see the aeroplane in the distance so I kept going that way FFS.
