Regex for Australian phone number validation
<p>I tried below regex for phone numbers validation but did not work properly, </p>

<pre><code>^([+61|0](2|4|3|7|8|)){0,2}([ 0-9]|[(]){2,3}([)]|[0-9]){6}([ ])[0-9]{7,20}$
</code></pre>

<p>Here are examples I expect to pass validation</p>

<pre><code>+61(02)89876544
+61 2 8986 6544
02 8986 6544
+61289876544
0414 570776 
0414570776
0414 570 776
+61 414 570776
+61 (0)414 570776
</code></pre>

<p>below characters also be accepted.
