When CommSec oscillates to show the (incorrect) Close of $5.32 it also shows Open $5.37, High $5.37, and Low $5.28. All of these data points relate to last Friday's price action (04/08). You can see it in the Trade History.
Still no idea why CommSec's Quote Page is currently oscillating between today's and last Friday's price summary data...
