Hey there GodaddyWindowsHosting - I was taking a look at the situation and I happened to notice the site did not throw any errors when using http://www.investland.com.au/index.php/faqs/
This leads me to believe there is another rewrite rule, possibly in a different web.config file, that is influencing how the redirect is done. I would recommend adding a <clear /> line directly under your <rules> tag - Here is an example of how I would recommend you form the web.config:
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<system.webServer>
<rewrite>
<rules>
<clear />
<rule name="wordpress" patternSyntax="Wildcard">
<match url="*"/>
<conditions>
<add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true"/>
<add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true"/>
</conditions>
<action type="Rewrite" url="index.php"/>
</rule></rules>
</rewrite>
</system.webServer>
</configuration>
