I'm not sure that your xamax.com.au SPF details are good.
xamax.com.au: "v=spf1 *ip4:184.108.40.206* +include:retailspf.smtp.com ?all"
retailspf.smtp.com: "v=spf1 ip4:220.127.116.11/19 ip4:18.104.22.168/20 ~all"
but the sending address at syd.hostingplatform.net.au is 22.214.171.124.
You could try changing the ip4:126.96.36.199 to ip4:188.8.131.52/24.
You might also want to set up a DMARC record so that you can receive
reports of messages that fail SPF/DKIM/ARC checks.
Yahoo is one of the fussiest, but also seems to permit the most real spam...
