$_POST varaible is not being populated with newly created 'page' data. Any ideas?

Trying to access the $_POST variable in this function to create an Audit post but the variable is not being sent through!

Code below:

<?php

// BUG: $_POST variable is not populated but only on the first save...
function sliced_create_audit_trail( $post_id ) {

    global $post;

    // verify if this is an auto save routine. 
    // If it is our form has not been submitted, so we dont want to do anything
    if ( defined( 'DOING_AUTOSAVE' ) && DOING_AUTOSAVE ) return;

    /* Get the post type object. */
    //$post_type = get_post_type_object( $post->post_type );

    /* Check if the current user has permission to edit the post. */
    //if ( !current_user_can( $post_type->cap->edit_page, $post_id ) ) return $post_id;

    // OK, we're authenticated: we need to find and save the data

    /* Get the post type object. */
    if ( $_GET['post_type'] == 'page' && current_user_can( 'edit_pages' )  ) {

        // unhook this function so it doesn't loop infinitely
        remove_action('save_post', 'sliced_create_audit_trail');

        // If this is just a revision, don't send the email.
        if ( wp_is_post_revision( $post_id ) ) return;

        $newPost = array(
              'post_title'     => wp_strip_all_tags( $_POST['page_title'] ), // The title of your post.
              'post_type'      => 'sliced_audit_cpt',// Default 'post'. made, in GMT.
        ); 

        wp_insert_post( $newPost );

        // re-hook this function
        add_action('save_post', 'sliced_create_audit_trail');

    }
    return $post_id;
}
add_action( 'save_post', 'sliced_create_audit_trail' );

?>

Don't worry!

The $_post variable is not availble on the initial save. Have to use global $post_data instead.

Or, as the codex points out:

"save_post is an action triggered whenever a post or page is created or updated, which could be from an import, post/page edit form, xmlrpc, or post by email. The data for the post is stored in $_POST, $_GET or the global $post_data, depending on how the post was edited. For example, quick edits use $_POST.

Since this action is triggered right after the post has been saved, you can easily access this post object by using get_post($post_id)"

<?php 

function sliced_create_audit_trail( $post_id ) {

    /* Get the post type object. */
    $the_post = get_post($post_id);

    // verify if this is an auto save routine. 
    // If it is our form has not been submitted, so we dont want to do anything
    if ( defined( 'DOING_AUTOSAVE' ) && DOING_AUTOSAVE ) return;

    // OK, we're authenticated: we need to find and save the data

    if ( $the_post->post_type == 'page' && current_user_can( 'edit_pages' )  ) {

        // unhook this function so it doesn't loop infinitely
        remove_action('save_post', 'sliced_create_audit_trail');

        // If this is just a revision, don't send the email.
        if ( wp_is_post_revision( $post_id ) ) return;

        $newPost = array(
              'post_title'     => $the_post->post_title, // The title of your post.
              'post_type'      => 'sliced_audit_cpt',// Default 'post'. made, in GMT.
        ); 

        wp_insert_post( $newPost );

        // re-hook this function
        add_action('save_post', 'sliced_create_audit_trail');

    }

    return $post_id;

}
add_action( 'save_post', 'sliced_create_audit_trail' );

?>
