stock_id cannot be null SQL error mysql Ver 14.14 Distrib 5.5.38

When trying to insert without stock_id value, I get the below error

mysql Ver 14.14 Distrib 5.5.38

2015-01-12T11:11:48+00:00 DEBUG (7): SQLSTATE[23000]: Integrity constraint violation: 1048 Column 'stock_id' cannot be null, query was: INSERT INTO australia_eparcel (website_id, dest_country_id, dest_region_id, dest_zip, condition_name, condition_from_value, condition_to_value, price, price_per_kg, delivery_type, charge_code_individual, charge_code_business, stock_id) VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)

Table does not accept NULL and does not default to 0 but instead throws an error.
code/community/Fontis/Australia/sql/australia_setup/mysql4-upgrade-2.3.0-2.4.0.php
$installer->run(
"ALTER TABLE {$this->getTable('australia_eparcel')}
ADD stock_id INT NOT NULL DEFAULT '0' COMMENT 'Warehouse ID for Multi Warehouse extension';"
);

Fixed by removing NOT NULL
