those figures you quote are only the yield. does not include capital appreciation. that is like quoting dividend yield for stocks but ignoring capital growth. bond prices rise ( capital growth ) when interest rates fall and vice versa. thus the Vanguard Australian Government bond index ETF has returned 11% in the year ending Nov 30th and Betashares CRED Australian investment grade corporate bond ETF has returned 15% ! nothing dodgy about it. that's what happens when interest rates fall.
