Ah! I used the following code inside the Loop within a customised template to achieve a similar effect:
<?php
$my_slug = get_permalink();
$args = array(
'numberposts' => -1,
'post_parent' => $post->ID,
'post_type' => 'page',
'post_status' => 'publish',
'orderby' => 'menu_order,title',
'order' => 'ASC'
);
$my_pagelist = &get_children($args);
if ($my_pagelist) :
foreach($my_pagelist as $my_child) :
$my_child_slug = $my_slug.$my_child->post_name.'/';
?>
<div class="sub_page">
<h3><?php echo $my_child->post_title;?></h3>
<?php echo $my_child->post_content; ?>
</div>
<?php endforeach; ?>
<?php endif; ?>
I then assigned the new template to the parent Page(s) as required. Just remember to changed the encoded ampersands above into a plain &.
Hope that helps.
